Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506980, here are decompositions:

83 + 33506897 = 33506980
179 + 33506801 = 33506980
239 + 33506741 = 33506980
317 + 33506663 = 33506980
383 + 33506597 = 33506980
401 + 33506579 = 33506980
431 + 33506549 = 33506980
503 + 33506477 = 33506980

Showing the first eight; more decompositions exist.
